Diagnosis

Diagnosis (Cyclocorinae): Members of the Philippine endemic subfamily Cyclocorinae can be distinguished from many members of the Elapoidea by possession of (1) intermediate body size (250–600 mm total length, excepting the unnamed lineage represented here by the specimen KU 337269); (2) 15 or 17 smooth scale rows at midbody; (3) a single row of subcaudals (shared by members of the genera Cyclocorus, Hologerrhum, and the unnamed lineage represented by KU 337269); (4) a distinctively elongate snout, characterized by the presence of enlarged anterior chin shields and an elongate loreal scale (shared by members of Oxyrhabdium and Myersophis); (5) a small number (5–6) of supralabials (Oxyrhabdium, Myersophis, and the unnamed lineage represented by KU 337269); and (6) markedly bulging, dorsally protruding eyes (Oxyrhabdium and Myersophis).

Phylogenetic definition (Cyclocorinae): Cyclocorinae refers to the clade originating in the last common ancestor of Oxyrhabdium leporinum (Günther, 1858), Cyclocorus lineatus (Reinhardt, 1843), the unnamed lineage represented by KU 337269, and all species that descend from that ancestor. It can also be conceived of as the largest crown-clade containing members of the genera Cyclocorus, Hologerrhum, Myersophis, and Oxyrhabdium, and members of the unnamed lineage represented by KU 337269.
